EVALUACION DE LA CALIDAD AGRICOLA DE CUATRO ENMIENDAS CALCAREAS EN UN SUELO ACIDO DERIVADO DE CENIZAS VOLCANICAS

The study described here involved an analysis of the agricultural quality of four types of limes applied to an acidic volcanic ash-derived soil. Soil samples were incubated in triplicate with 0, 1, 2, 3 and 6 g per kg-1 soil of each of the four limes. The soil samples corresponded to Valdivia soil series (Typic Hapludand). Following 20 days of incubation at 23 ºC, the effect of the type of lime on soil pH (0,1M CaCl2), exchangeable Ca (exCa), exchangeable bases (ExB), exchangeable Al (exAl) and aluminum saturation percentage (AlS %) was determined. To examine the effect of the type of lime on soil pH, exCa and exB, linear regressions were fitted to the data, and exponential equations were fitted to the data for exAl and Al %S. The t Student test was applied to the determined values of the slope (b) and curvature coefficient (k) to compare the behavior of different limes. The most sensitive acidity variable to differentiate between types of lime was the k value from exAl followed by k values from AlS % and b values from exCa and ExB. The least sensitive variable was found to be the b value from soil pH. These results are in agreement with the ENV values of the lime and predict agricultural quality behavior of each level type. This is most likely because of the characteristics of the incubation method, in terms of low temperature, which would have only allowed the small particle size of the limematerials to react completely as opposed to all of the lime material. This incubation method is different to other methods using high temperatures where bigger and smaller particles completely react giving results close to ECC values.

Este estudio evalúa la calidad agrícola de cuatro enmiendas calcáreas en un suelo ácido derivado de cenizas volcánicas. Para ello se hicieron incubaciones en triplicado de cada enmienda aplicada en dosis de 0, 1, 3 y 6 g por kg-1 de suelo. Se usó un suelo de la serie Valdivia (Typic Hapludand). Luego de 20 días de incubación a 23 ºC se midió el pH en CaCl2 0,01M, Ca intercambiable, (Ca-i) suma de bases, (S.B.), aluminio intercambiable (Al-i) y porcentaje de saturación de aluminio (%S.Al). El efecto de las dosis, sobre el pH, Ca-i y S.B. se ajustó a regresiones lineales y a ecuaciones exponenciales en el caso del Al-i y %S.Al. Los valores de la pendiente (b) y de los coeficientes de curvatura (k) se analizaron mediante prueba t de Student para comparar el comportamiento de las enmiendas. El parámetro de acidez de mayor sensibilidad para diferenciar el comportamiento de las cales fue el valor de k del Al-i. Le siguen el valor de k del %S.Al junto a la S.B y al Ca-i. El pH en CaCl2 presentó la menor sensibilidad. El efecto de las dosis sobre los parámetros de las ecuaciones se asimila al valor neutralizante efectivo (VNE) de las enmiendas y por lo tanto a su calidad agrícola. Esto es resultado del método de incubación de baja temperatura que privilegia la manifestación de los particulados más finos, de mayor reactividad, a diferencia de otros métodos que permiten una reactividad total y sus resultados se relacionan con los valores de CCE.
